So to compete with the 660 they jack up the power consumption to beyond 670 levels? I'd say it's ironic how things had swapped, but even when nvidia cards were the more power hungry they at least offered the top performance.

By the way, I can do 1000Mhz with 1.056... Does this mean probably my card consumes less than Wizard's reference card in those graphs ( the ref at 800Mhz with 1.07 ) ?

I'm curious because I really do care for power consumption. This was the reason I didn't get 7970, back then.

So... There is absolutely no reason to try this BIOS, right? Why to increase my Voltage to 1.112 ( 1.031 default at 900Mhz and I can easily undervolt at least 1.006 )? I can run with this voltage at 1060-1070Mhz normally.

Updated my XFX FX-795A-TDFC with no problems (used atiflash DOS on USB stick and shortened the BIOS filename to the traditional 8.3 character DOS style). It looks like this BIOS raised the voltage a lot, although I sort of wanted that to an extent so I could just use Overdrive without Afterburner getting in the way and causing conflicts with Overdrive (I'm guessing that is where most of my display driver crashing and weird screen spazzing is coming from). Going to try Nexuiz tomorrow and hope my card doesn't hit 90c at 1GHz like it was (wouldn't be surprised if it did, the XFX 7950 DD cooler sucks).

I'm almost tempted to buy one of those expensive Accelero coolers but the stock card barely fits in my Rosewill Challenger as it is.

I tried this update on my Sapphire HD7950, which GPU-Z sees as having the same Device ID as the ATI HD 7950, different sub vendor though being Sapphire.
Well, it bricked my HD7950, luckily I had an older VGA which I used as primary while I forced a reflash of the original BIOS in my Sapphire HD7950. It would seem Sapphire support is crap, it would have been much more professional from their side to put a download link for the needed BIOS update in the page of each HD7950 they make.

You know all of them don't put their bios code up as its a risky task for the end user to do anyway. I'm not sure why you are trying to defame the company via libel. I hope you learned your lesson the hard way because honestly you didn't know what you were doing and you bitched that the bios flash failed.

So you flash the card with a bios that wasn't designed for it and then actually blame Sapphire for your mistake when it breaks? You've blown the warranty and don't deserve any support, so how good or bad it is becomes irrelevant.

This BIOS was advertised as good for HD7950 following standard PCB. Clearly this is not the case as it is not working for a Sapphire with the same identical device ID.
I think you watched one too many episodes of Ally McBeal or Damages, but at least you enriched your vocabulary with big words like "libel"
Here's the funny thing: it's not libel if it's damn true! Sapphire is making fine VGA, especially considering they are pretty much the cheapest ATI option on the market. But after sales support is clearly lacking.
